1      Introduction

This document specifies the SOAP protocol bindings for OBIX.

1.1 Terminology

The key words “MUST”, “MUST NOT”, “REQUIRED”, “SHALL”, “SHALL NOT”, “SHOULD”, “SHOULD NOT”, “RECOMMENDED”, “MAY”, and “OPTIONAL” in this document are to be interpreted as described in RFC2119.

1.2 Normative References

RFC2119                 Bradner, S., “Key words for use in RFCs to Indicate Requirement Levels”, BCP 14, RFC 2119, March 1997. http://www.ietf.org/rfc/rfc2119.txt.

2      SOAP Binding

The SOAP binding maps a SOAP operation to each of the three OBIX request types: read, write and invoke. Like the HTTP binding, read is supported by every object, write is supported by objects whose writable attribute is true, and invoke is only supported by operations. Inputs and outputs of each request are specific to the target object.

Unlike the HTTP binding, requests are not accessed via the URI of the target object, but instead via the URI of the SOAP server with the object’s URI encoded into the body of the SOAP envelope. The examples given in this specification are non-normative. The additional documents (WSDL file and the OBIX schema) provide a normative specification.

2.1 SOAP Example

The following is a SOAP request to an OBIX server’s About object:

<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/">

 <env:Body>

  <obixWS:read xmlns:obixWS=" http://docs.oasis-open.org/obix/ns/201410/wsdl"

               xmlns="http://docs.oasis-open.org/obix/ns/201410/schema"

        href="http://localhost/obix/about" />

 </env:Body>

</env:Envelope>

An example response to the above request:

<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/">

 <env:Body>

  <obixWS:response xmlns:obixWS="http://docs.oasis-open.org/obix/ns/201410/wsdl"

                   xmlns="http://docs.oasis-open.org/obix/ns/201410/schema">

    <obj name="about"

         href="http://localhost/obix/about/">

      <str name="obixVersion" val="1.1"/>

      <str name="serverName" val="obix"/>

      <abstime name="serverTime" val="2006-02-08T09:40:55.000+05:00:00Z"/>

      <abstime name="serverBootTime" val="2006-02-08T09:33:31.980+05:00:00Z"/>

      <str name="vendorName" val="Acme, Inc."/>

      <uri name="vendorUrl" val="http://www.acme.com"/>

      <str name="productName" val="Acme OBIX Server"/>

      <str name="productVersion" val="1.0.3"/>

      <uri name="productUrl" val="http://www.acme.com/obix"/>

    </obj>

  </obixWS:response>

 </env:Body>

</env:Envelope>

2.2 Error Handling

The OBIX specification defines no SOAP faults. If a request is processed by an OBIX server, then a valid OBIX document SHOULD be returned with a failure indicated via the err object.

2.3 Security

Refer to the recommendations in WS-I Basic Profile 2.0 for security [WS-I].

2.4 Localization

SOAP bindings SHOULD follow localization patterns defined for the HTTP binding when applicable (see Section [OBIX REST].

2.5 WSDL

In the types section of the WSDL document, the OBIX schema is imported. Server implementations might consider providing the schemaLocation attribute which is absent in the standard document.

Each instance will have to provide its own services section of the WSDL document. The following is an example of the WSDL service element:

<wsdl:service name="obix">

  <wsdl:port name="obixPort" binding="tns:obixSoapBinding">

    <soap:address location="http://localhost/obix/soap"/>

  </wsdl:port>

</wsdl:service>

Standard OBIX WSDL is:

<wsdl:definitions targetNamespace="http://docs.oasis-open.org/obix/ns/201410/wsdl"

  xmlns="http://docs.oasis-open.org/obix/ns/201410/wsdl" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
